Zostavax
Zostavax (pronounced zos-ta-vaks) is a vaccine used to prevent shingles in adults 50 years of age and older.
Etymology
The name "Zostavax" is derived from "Zoster Vaccine Live", indicating its use and the live, but weakened, virus it contains.
Usage
Zostavax is a live vaccine that helps to prevent shingles, a painful skin rash caused by the varicella zoster virus, the same virus that causes chickenpox. The vaccine works by boosting the immune system's response to this virus, helping to protect the patient from shingles and its complications.
Effectiveness
Zostavax reduces the risk of developing shingles by about 51% and postherpetic neuralgia by 67%. It is less effective in older adults, and its protection lasts about five years.
Side Effects
Common side effects of Zostavax include redness, pain, itching, swelling, hard lump, warmth, or bruising where the shot was given. Other side effects include fever, joint or muscle pain, or skin rash.
Contraindications
Zostavax should not be given to people with weakened immune systems due to conditions like AIDS, treatment with drugs that affect the immune system, or cancer treatment. It is also not recommended for pregnant women or people with a history of severe allergic reaction to gelatin, the antibiotic neomycin, or any other component of the vaccine.
